Well, usually in such a fanfic, at first Anko might be reluctant to be Naruto's servant. But as time goes by, she could start to see Naruto's good qualities like his determination and kindness. Maybe Naruto also shows her respect despite her being in a servant role, which gradually makes her more accepting of the situation.
In this fanfiction, a significant plot point might be the initial encounter that leads to Anko becoming Naruto's servant. It could be a result of a bet, a mission gone wrong, or some kind of magical event. Then, as Anko starts her new role, there could be plot points around her learning to follow Naruto's orders while still maintaining her own personality. Also, the fanfic could explore how Naruto and Anko work together to overcome challenges like fighting powerful enemies or solving mysteries in the ninja world. Additionally, the reactions of their friends and foes to this relationship would also be important plot points.
In this fanfiction, perhaps there is an evil force that wants to use Anko to get to Naruto. By making Anko Naruto's slave, they hope to manipulate Naruto. But Naruto and Anko end up outsmarting the evil force. Naruto helps Anko regain her freedom and in the process, they both learn important lessons about friendship, trust and the value of freedom. Also, Anko might learn to respect Naruto more and Naruto might see a different side of Anko that he didn't before.
Well, Naruto might learn some unique jutsu from Anko. Since Anko is known for her snake - related techniques, Naruto could incorporate some of those elements into his own fighting style. Maybe he'd become even more unpredictable in battles.
Perhaps the Twi'lek becomes Naruto's servant due to a debt owed to Naruto. In the Naruto universe, the concept of honor and repaying debts is important. So, the Twi'lek could follow Naruto around, gradually learning about his ninja way. The Twi'lek could also introduce some of their own cultural elements, like unique fighting styles or forms of communication, which Naruto and his friends could incorporate into their own techniques.
There's a chance that it could be a group of rogue ninjas. They want to use Anko's new position as Naruto's slave to infiltrate Konoha. They might be after some secret technique or valuable information. Naruto and Anko must work together to expose this group and save the village while also dealing with Anko's slavery situation.
One possible plot could be that Anko, perhaps due to a strange jutsu gone wrong, is transformed into a small animal. Naruto, being the kind - hearted person he is, takes her in as a pet. He tries to find a way to reverse the transformation while they go on various adventures together. Anko, in her new form, might initially be frustrated but gradually grows to like Naruto's company.
One possible plot could be that Anko, for some reason like a bet or a mission gone wrong, has to serve as Naruto's maid. At first, Naruto is really awkward about it. He's not used to having someone wait on him. But Anko, with her tough and sassy personality, tries to do things her own way. She might cook some really strange and spicy food for Naruto that he has to learn to get used to. And along the way, they could develop a unique friendship as Naruto starts to see Anko in a different light, not just as the tough ninja she always was.
The story might be about how Mikoto, as Naruto's servant, helps him grow in power. She could train him in ways that the regular Konoha teachers can't. Since she comes from the Uchiha clan, she might have unique knowledge about chakra control and jutsu that she imparts to Naruto. Also, their relationship could develop from a master - servant dynamic to a deep friendship.
One idea could be that in this fanfiction, Fem Gaara is in debt to Naruto for saving her life. As a result, she decides to become his servant. This could lead to many comical situations where Naruto, being his usual clumsy self, has no idea how to handle having a servant. For example, he might accidentally give her tasks that are inappropriate or too easy, and Fem Gaara has to figure out how to deal with it while still maintaining her pride.
